Description

The present invention relates to a locking device for insertion into a recess in a device to be locked, the locking device having an actuating bolt and a locking part which can be connected in a rotationally fixed manner to the actuating bolt and can be locked and / or unlocked by rotating the actuating bolt, the locking part in can be fastened to the actuating bolt in several positions. The invention further relates to the use of such a locking device as a transport lock of a body part to be locked, such as a device housing door of a security-sensitive gaming, betting and / or entertainment device.

On various security-sensitive devices such as gaming machines, betting or entertainment machines, end customers or device operators would like to be able to lock the security-relevant housing components with their own locks in order to be able to guarantee compliance with their own individual security requirements or to be able to exclude security gaps, for example during transport . At the gaming, betting and / or entertainment machines mentioned, this can be, for example, the appliance door, which can be locked with a user-specific lock. Depending on the device, this can also be, for example, a lid or a flap with which a money storage unit in the The interior of the device can be closed, or a pull-out drawer or a drawer on which a safety-relevant component is provided.

Such devices to be locked should nonetheless already be provided with locking devices by the manufacturer, for example in order to prevent unwanted opening or unauthorized opening during transport or to be able to carry out a functional test during removal, which can sometimes require proper locking of doors and flaps. In order to ensure proper locking on the one hand, but on the other hand to facilitate the conversion of the locking device often carried out by the end customer, it would be desirable to be able to insert a fully functional locking device into the recess of the device to be locked, in which the lock desired by the end customer is installed and at the same time to enable an authorized user to easily disassemble. It would also be desirable to be able to use the locking device for different recesses or devices to be locked, since the recesses mentioned are sometimes ordered by different customers in different geometries in order to fit exactly with the customer-specific, final locking device. Like the scriptures, for example US 2005/0192101 , US 2006/0012184 or US 2010/0117384 show, door locks of gaming machines can be configured in very different ways, so that the door or housing recesses, into which these locks must be inserted, can be designed very differently.

The scriptures CA 2691923 , US 3,593,458 or US 4,718,195 show transport locking devices by means of which doors can be locked for transport to the end customer, the corresponding locking devices can be inserted into the door or door frame recess, in which the final door lock is then installed. However, these transport locking devices are rather only of a provisional nature and are not really fully functional in the sense that the door can be locked several times by means of an actuating element that can be handled conventionally, such as a rotary knob or a slide. and would be unlocked. In addition, these transport locking devices require an individual adaptation to the device to be locked or they can hardly be used for different doors or used in differently configured recesses.

The font WO 2008/119541 shows a locking device for a door in which an actuating pin in the form of a rotatable mandrel can be inserted into a bearing recess of a fitting component, with an actuating handle being plugged onto the mandrel from one side and the mandrel itself being inserted non-rotatably into a gear washer, which is a Rotary movement of the mandrel is converted into a sliding movement of the actual locking part of the fitting.

The scriptures DE 39 32 939 and CH 553 903 show further locking devices in which the locking plate is screwed onto the actuating bolt. Scripture also shows US 4,492,394 a locking device in which the locking plate can be attached to the actuating bolt in different axial positions. The locking plate is also screwed onto the actuating bolt and secured against rotation at a certain screw height by a slip clutch, at least as long as the rotary actuation forces do not exceed the escapement of the slip clutch. If the actuating bolt is turned over while the locking plate is in contact, the above-mentioned slip clutch slips, so that the locking plate is screwed to the bolt and is thus axially adjusted.

DE 297 07 314 U1 discloses a locking device which discloses the features of the preamble of claim 1.

DE 94 01 456 U1 relates to a closure, in particular for storage space covers or cladding in z. B. motor vehicles, which has an actuating head, a bolt connected to it in a rotationally fixed manner and at least one releasable latching between the actuating head and the bolt.

The revelations of the WO 91 / 14845.A1 , BE 806 882 A1 and the US 4 910 982 A. also show a locking device in which an actuating pin can be releasably engaged with a locking part by a locking means.

The present invention has for its object to provide an improved locking device of the type mentioned, which avoids disadvantages of the prior art and further develops the latter in an advantageous manner. The locking device should preferably be able to be inserted in different recesses and ensure a fully functional locking even with multiple actuation, but at the same time, however, enable simple, tool-free disassembly in order to simplify the exchange of the locking device by an authorized end customer.

This object is achieved according to the invention by a locking device according to claim 1 and the use of such a locking device according to claim 14. Preferred embodiments of the invention are the subject of the dependent claims.

In order to be able to easily adapt the locking device to recesses of different depths or to devices of different thicknesses to be locked, the locking part can be fixed to different sections of the actuating bolt, so that the locking device has a different length. According to the invention, the actuating bolt and the locking part have releasable locking means with a plurality of locking positions for locking the locking part in several axial positions on the actuating bolt. The latching means comprise interlocking interlocking contours that can be pushed over one another in the longitudinal direction of the actuating bolt with elastic deformation and can be latched into one another by elastic springing back transversely to the longitudinal direction of the actuating bolt, so that the locking part is held axially on the actuating bolt in the respective latched position. Depending on how thick the body is, in which the recess is formed, into which the locking device is to be inserted, or depending on how large the distance of the counterpart to be caught by the locking part from said recess is, the locking part can be fixed in a different axial position on the actuating bolt. As a result, the locking device can easily be used for various devices to be locked, the locking part being fixed to the actuating bolt when it is pushed onto one another in the respectively desired position by the latching means itself. The locking part and the actuating bolt only need to be plugged onto one another in the axial direction of the actuating bolt and moved relative to one another until the desired position is found, in which the latching means then lock.

The locking means work elastically in order to be able to be locked and unlocked several times and a multiple reuse of the locking device at various devices to be locked. The locking means are designed to be non-destructively detachable, so that the locking device can be removed in a simple manner, preferably without tools, by releasing the locking part from the actuating bolt. This considerably simplifies dismantling by an authorized end customer.

The latching means can basically comprise differently shaped latching contours. In an advantageous development of the invention, the latching contours of the latching means comprise at least one latching projection which is raised transversely to the longitudinal direction of the actuating bolt, and at least one latching depression which is recessed transversely to the longitudinal direction of the actuating bolt, the latching recess and the latching projection being matched to one another, in particular in a complementary manner are designed to each other so that the locking projection can be sunk into the locking depression and can snap into it. In order to implement the aforementioned multiple locking positions and to be able to fix the locking part to the actuating bolt in different axial positions, the locking contours advantageously comprise a plurality of detent depressions which are arranged one behind the other and / or spaced apart in the longitudinal direction of the actuating bolt, so that the at least one detent depression can optionally be in one of the several notches can snap into place. Alternatively or additionally, a plurality of such latching projections can also be provided, one of which can optionally snap into the at least one latching depression, wherein the said plurality of latching projections can be arranged one behind the other and / or at a distance from one another in the longitudinal direction of the actuating bolt.

The latching contours, in particular in the form of the latching projections and depressions mentioned, can be undercut when viewed in the longitudinal direction of the actuating bolt, the undercuts on the locking part and on the actuating bolt being matched to one another so that a pair of undercuts in engagement engages behind one another transversely to the longitudinal direction of the actuating bolt . Due to the undercut of the locking contours - in the longitudinal direction considered the actuating bolt - in the locked position to overlap the respective locking contour pair.

At least one of the latching contours mentioned, for example the latching projection or the latching depression or both, are themselves designed to be elastic or are arranged on an elastically designed part or are arranged on a movably mounted, elastically prestressed part, so that at least one of the latchable latching contours is so far transverse for disengaging is movable to the longitudinal direction of the actuating bolt that the locking contour can be pushed over the other locking contour.

In an advantageous development of the invention, the latching means can comprise a ribbed and / or corrugated surface structure on the actuating bolt and / or on the locking part, which surface structure with a counter-contour piece with elastic and / or plastic deformation of the surface structure and / or the mentioned counter-contour piece when the locking part and Actuating bolt can be brought into positive locking engagement. Such a ribbed or corrugated surface structure allows fine adjustment of the desired axial position of the locking part and the actuating bolt relative to one another. Advantageously, the ribbed surface structure on the actuating pin can comprise a plurality of holding ribs which are staggered in the longitudinal direction of the actuating pin, preferably at least partially on the circumference of the actuating pin, whereby the counter-contour piece can comprise at least one holding rib on the locking part, which advantageously advantageously at least partially on an inner circumferential side of the locking part, in particular in a through recess which can be plugged onto the actuating bolt. The staggered arrangement of the retaining ribs on the actuating pin allows a large adjustment range. At the same time, if the counter-contour piece is provided in a passage recess, a sufficiently tight fit can be ensured in order to apply the holding forces.

In an advantageous further development of the invention, the ribbed or corrugated surface structure or the counter-contour piece interacting therewith can be designed in such a way that different actuating and holding forces result, in particular such that the force required for plugging the locking part and actuating bolt onto one another is smaller than the force, which is necessary for the opposite, axial release of the locking. Such a configuration of the corrugation or ribbing can combine a high level of operating convenience during assembly with sufficiently high holding forces. The relatively low attachment forces enable simple attachment by hand and thus also a precise, coordinated reaching of the desired position, while conversely the higher unlocking forces ensure that the locking part is adequately held on the actuating bolt and secured against slipping down. In particular, the holding ribs provided in staggered fashion on the actuating bolt and / or the holding rib provided on the counter-contour piece can be sawtooth-shaped, i.e. have flanks with different degrees of inclination, which get caught with the respective counter-contour in such a way or come into engagement in such a way that plugging onto one another with elastic and / or plastic deformation of the components involved is easier than pulling apart or pushing in the opposite direction.

The locking device can in principle be received or stored in various ways in the recess of the component to be locked. For example, the actuating bolt can be mounted or supported directly in the recess, in particular when the said recess is contoured in a rotationally symmetrical manner, which is not a requirement, however. For example, the actuating bolt can comprise a corresponding shoulder, which forms an axial bearing surface, and / or a, for example, thickened, in particular cylindrical, bearing head, which is supported on the circumferential side on an inner contour of the recess or forms a radial bearing surface. However, in order to enable easier adaptation to different recesses and to achieve better rotatability, according to the invention a rotary guide part is assigned to the actuating pin, which fits precisely into the mentioned recess can be inserted and has latching means for latching on an edge contour surrounding the recess.

The actuating bolt can advantageously be rotatably received in the rotary guide part, in which case the rotary guide part can be designed such that the rotary guide part can be locked in the recess in a rotationally fixed manner. In principle, however, the mentioned rotary guide part could also be joined to the actuating bolt in a rotationally fixed manner and in this case be rotatably mounted in the recess or in an intermediate bearing and / or adapter piece. With a rotatable connection between the actuating pin and the rotary guide part, however, the fixing of the rotary guide part in the recess is simplified.

According to the invention, the locking means of the rotary guide part comprise at least one locking projection projecting radially from the body of the rotary guide part, which locking projection is radially elastically deformable when the rotary guide part is inserted axially into the recess and, after passing through the recess, snaps back radially so that the locking projection retracts or retracts. Pulling out of the rotating guide part prevented from the recess. Advantageously, the rotary guide part can be designed and / or intended to be inserted into the recess from an outside of the component to be locked or the associated body part, so that the locking projection comes to rest on the inner wall side or springs back in the locking state , so that unauthorized loosening of the locking projection is prevented or the locking projection is only accessible and can be opened when the device to be locked is in the open position. In order to be able to fit the rotary guide part in recesses of different depths or to be able to use them for body parts of different thicknesses, the latching means of the rotary guide part according to the invention comprise a plurality of latching projections which are staggered one behind the other in the longitudinal direction of the rotary guide part in such a way that a different one is used for edge contours of different thicknesses Locking projection can be snapped precisely. Regardless of the respective edge contour thickness, the latching is automatically activated such that when the rotary guide part is inserted, several of the latching projections arranged in a row are first pushed back and one or more latching projections spring back until the end position is reached, while one or more latching projections remain pushed back since they Do not leave the recess or its narrow section again. The rotary guide part is then held in the recess with a precise fit by at least one of the recessed locking projections which come into the locking position. By providing a plurality of latching projections which are staggered one behind the other in the direction of insertion of the rotary guide part, the locking device can be adapted in a simple manner to body parts of different thicknesses or recesses of different depths or can be used without problems for such differently configured components.

The actuating bolt can be freely rotatably received in the rotary guide part or can be rotated without being fixed over the entire, possibly limited range of rotation. However, in order to signal an operator when the unlocking position or the locking position has been reached, in a further development of the invention, latching means can be provided on the rotary guide part and / or on the actuating bolt for latching the actuating bolt in an unlocked rotational position and / or in a locked rotational position, wherein the said locking means advantageously snap in elastically in the respective locking position and, in the unlocked position, enable the actuating bolt to be rotated with as little resistance as possible. In an advantageous development of the invention, the latching means mentioned can have at least one transverse rib and / or at least one transverse groove on an axial bearing surface of the rotary guide part and / or the actuating bolt and / or at least one longitudinal rib and / or at least one longitudinal groove on a radial bearing surface of the rotary guide part and / or the Include actuating bolt. In an advantageous development of the invention, at least one transverse rib running transversely to the axis of rotation and one transverse groove also running transversely can be provided on the end of the rotary guide part and on the end of the actuating bolt be, which then, when they come into alignment with each other, snap into each other, so that the rotational position of the actuating bolt is fixed relative to the rotary guide part. The actuating pin and the rotary guide part can be axially elastically biased to one another in the longitudinal direction, for example by a spring device or by a certain elasticity of the actuating pin, so that the transverse rib is pulled into said transverse groove in the corresponding rotational position and, conversely, disengagement is possible by rotating the actuating pin . The actuating bolt can also be axially locked on the rotary guide part, the latching means being able to be designed in such a way that the actuating bolt has a certain elasticity axially out of the latching position, ie can be pulled out a little from the latching position and is retracted again by the latching means.

The latching means for axially latching the actuating bolt on the rotary guide part can, for example, have a circumferential groove and a circumferential projection cooperating therewith, which can have oblique or rounded flanks in order to achieve the elasticity or spring effect mentioned.

In order to be able to secure several positions, for example the unlocked position and the locked position of the locking part by latching, several transverse grooves can advantageously be provided for a transverse rib and / or a symmetrical arrangement of transverse grooves and transverse ribs can be provided which can be brought into alignment with one another in different rotational positions are.

The actuating pin can advantageously comprise a circular-cylindrical guide section, possibly also a plurality of circular-cylindrical guide sections with undercuts arranged between them, which at least one guide section rotatably supports the actuating pin in a recess, in particular in a recess in said rotary guide part, so that smooth-running rotary actuation of the actuating pin is made possible. On the other hand, the actuating bolt can be arranged on a bolt section that is displaced in the axial direction relative to the circular cylindrical guide section of the locking with the locking part serving locking portion, which locking portion may have a cross-sectional shape deviating from the circular shape. Advantageously, the cross-sectional contour of the latching section is dimensioned or configured such that, when viewed in the longitudinal direction of the bolt, it lies within the contour of the circular-cylindrical guide section, so that the latching section can be pushed through the bearing recess for rotatable mounting of the actuating bolt without getting caught. In particular, said latching section of the actuating bolt can have a circumferential flattening, advantageously two oppositely arranged flattenings, on which flats the aforementioned latching means can be provided for latching the locking part and actuating bolt.

In order to achieve simple assembly and protection against unauthorized dismantling at the same time, an advantageous development of the invention provides that the actuating bolt has an actuating head and can be inserted from one side into the recess of the device to be locked such that the actuating head is on one side of the The recess comes to rest and the locking part can be placed on the actuating bolt from an opposite side of the recess. As a result, the body part having the recess of the device to be locked is sandwiched between the actuating head of the actuating bolt on the one hand and the locking part to be rotated on the other hand, so that the locking part is not accessible in the closed state of the body part. Apart from this, the aforementioned sandwich-like receptacle of the body part to be locked between the actuating head and the locking part can also be used to ensure that the locking device on the body part is secured against undesired slipping out or pulling out, for example if the locking of the aforementioned rotary guide part at the edge contour of the recess fails. For this purpose, the locking part, viewed in the direction of rotation of the locking device, can be made larger than the recess and / or can be arranged to protrude beyond the recess on the edge side, so that the locking part on the actuating bolt prevents the locking device from being pulled out. In a further development of the invention, said locking part can be a radially protruding from the actuating bolt, approximately plate-shaped locking part, the radial projection beyond the actuating bolt can exceed the radius, preferably also the diameter of the recess in the component to be locked.

Fig. 7:

a perspective view of a game device with a locking device according to the preceding figures.

As the figures show, the locking device 1 can essentially consist of only three components, an essentially spike-shaped actuating pin 6 being able to be inserted through a rotary guide part 8, so that the actuating pin 6 is rotatably received in the said rotary guide part 8 and with one from the rotary guide part 8 protruding bolt section can be connected in a rotationally fixed manner to, for example, a plate-shaped locking part which, depending on the rotational position, engages behind or releases a contour piece of a locking latch to be captured.

Said actuating pin 6 can, like the Figures 1 and 2 show, comprise an at least approximately cylindrical guide section 6a, to which a locking section 6b deviating from the circular shape can be connected. Said locking section 6b can - cf. Fig. 2 - Continue approximately the contour of the guide section 6a, but in this case have at least one, preferably two opposing flats, on which locking means 10 are provided for locking with the locking part 7. The cross-sectional contour of the actuating bolt 6 in the latching section 6 is advantageously dimensioned such that it is viewed within the longitudinal direction of the actuating bolt 6 Cross-sectional contour defined by the guide section 6a is located, so that the actuating pin 6 can be pushed through the bearing bore 23 in the rotary guide part 8 without interference.

On the side of the guide section 6a opposite the mentioned latching section 6b, the actuating bolt 6 has an actuating head 17 which is significantly enlarged in diameter compared to the guide section 6a, in particular can have the shape of an approximately plate-shaped widening. How Fig. 3 (a) shows, the actuating head 17 can comprise a passage recess 24, for example in order to be able to lock the actuating head 17 with a padlock or to be able to connect an actuating handle to the actuating head 17 in a rotationally fixed manner.

The actuating head 17 forms, with its end face facing the rotary guide part 8, an axial bearing surface 19 which interacts with an axial bearing surface 20 on the rotary guide part 8, which axial bearing surface 20 can be formed by an end face of the said rotary guide part 8. Said axial bearing surfaces 19 and 20 can abut one another in order to define the axial position of the actuating bolt 6 relative to the rotary guide part 8. As the Figures 1, 2 and also show 6 (a), second latching means 18 are provided on said axial bearing surfaces 19 and 20 for rotationally latching the actuating bolt 6 on the rotary guide part 8, which second latching means 18 on the one hand comprise a projecting transverse rib 21 and a plurality of transverse grooves 22 adapted to the transverse rib 21 that run in different rotational orientations. In the embodiment shown, the transverse rib 21 is provided on the actuating head 17, while the transverse grooves 22 are provided in the rotary guide part 8. In principle, however, the transverse rib could also be provided on the rotary guide part 8 and the transverse grooves on the actuating head 17, although the arrangement of the transverse rib 21 on the actuating head 17 shown in the figures is preferred in particular in the approximately plate-shaped contouring of the actuating head 17 shown in the figures to achieve a more uniform support of the axial bearing surfaces 19 and 20 against each other over the entire range of rotation.

For example, transverse grooves 22 arranged at right angles to one another can be provided on the end face of the rotary guide part 8 in order to be able to lock the locking part 7 in positions which are rotated at right angles to one another, which rotary positions can advantageously correspond to a locking position and an unlocked position.

The latching section 6b of the actuating bolt 6 can, as intended, be introduced into a counter-contour piece 13 on the locking part 7 which is adapted thereto, it being possible advantageously for said counter-contour piece 13 and the latching section 6b to be configured in such a way that they can be axially pushed in in the longitudinal direction of said actuating bolt 6 can be inserted into the opposite contour. In particular, said counter-contour piece 13 can be formed by a through recess of the locking part 7 which is adapted in diameter to the latching section 6b of the actuating bolt 6.

The latching means 10 for latching the bolt part 7 and the actuating bolt 6 are advantageously designed such that they automatically snap in when the bolt part 7 and the actuating bolt 6 are plugged together. The latching means 10 comprise latching contours provided on the locking part 7 and on the actuating bolt 6, which are each undercut in the longitudinal direction of the actuating bolt and are matched to one another in such a way that an undercut pair in engagement in a respective latching position can engage behind one another and is viewed in the longitudinal direction of the actuating bolt at least partially covered. In particular, latching contours projecting or countersunk, for example in the form of a latching tongue and a latching depression, can be formed as latching contours transversely to the longitudinal direction of the bolt, which can be pushed over one another with elastic deformation and / or deflection transversely to the longitudinal direction of the bolt in the longitudinal direction of the bolt and can be formed on the latch part 7 and on the actuating bolt 6 by elastic snap back or spring back transversely to the longitudinal direction of the bolt can snap into each other and thus can come into positive locking engagement by which the locking part is axially fixed to the actuating pin.

How Fig. 1 shows, the latching means 10 on the one hand on the actuating pin 6, in particular on the flats 6c of the latching section 6b of the actuating pin 6, can comprise a corrugated or ribbed surface structure 11, which can comprise a plurality of sawtooth-shaped retaining ribs 12, one behind the other in the longitudinal direction of the actuating pin 6 are staggered, cf. Fig. 1 . The sawtooth profile of the holding ribs 12 is advantageously oriented such that the surface structure 11 mentioned can be inserted into the passage recess of the locking part 7 with relatively low forces, but can only be pulled out in the opposite direction under increased forces or opposes increased forces when pulled out.

The counter-contour piece 13 on the locking part 7 can also have a similarly ribbed or corrugated surface structure. Like the drawn version after Fig. 1 shows, the locking means 10 on the counter contour piece 13, however, can also have only a single holding rib 14. Depending on the design of the fits and depending on the choice of material, such a retaining rib could possibly also be dispensed with entirely, for example if the material of the counter-contour piece 13 is sufficiently soft so that the sawtooth-shaped retaining ribs 12 on the actuating bolt 6 dig into said counter-contour piece 13 or get caught on it. Conversely, it would also be conceivable to provide a corresponding, preferably sawtooth-shaped and / or corrugated and / or corrugated surface structure on said counter-contour piece 13 and to design the actuating bolt 6 free of a corrugated and / or corrugated surface structure, in particular if the bolt is of a sufficient size soft and / or flowable material, for example thermoplastic, is formed so that a surface structure on the counter-contour piece 13 can dig into the shaft of the, for example, completely cylindrical latching section of the actuating bolt or can hook onto it.

However, the latching contour formation shown in the figures is preferred both on the actuating bolt 6 and on the counter-contour piece 13 with interlocking latching contour projections or retaining ribs 12 and 14 which can be pushed over one another under elastic deformation and can be snapped into one another by elastic springback.

Due to the staggered holding ribs 12, the locking part 7 can be locked in different axial positions on the actuating pin 6, i.e. the locking part 7 can be plugged onto the actuating bolt 6 to a greater or lesser extent, in each case as desired, and secured in the respective position by latching the latching means 10, the retaining rib 14 in each case coming into positive engagement with another retaining rib 12.

As the Figures 1 and 2 show, the rotary guide part 8 can comprise an at least approximately cylindrical plug-in section 25 and an adjoining contact or head section 26 which projects radially over the plug-in section 25 and / or is of significantly larger diameter than the plug-in section 25. In particular, said head section 26 can form an abutment shoulder with which the rotary guide part 8 can be attached to an end edge contour of the recess into which the locking device 1 can be inserted. As the Figures 5 and 6 show, a component to be locked, such as the door 2 of a housing 3 of a gaming machine, but possibly also another body part such as a drawer, a flap or a cover, can comprise a recess 9 into which the locking device 1 can be inserted. Said recess 9 can in particular be a through recess which passes through a panel part of the device to be locked and which can be, for example, a cylindrical through hole.

How Fig. 6 (b) clarifies, the rotary guide part 8 with its insertion section 25 can be adapted to the aforementioned recess 9 in such a way that the insertion section 25 can be inserted into the recess 9 with a precise fit. In particular The outer diameter of the insertion section 25 can be adapted to the inner diameter of the recess 9 or its clear width, so that there is a precise fit. Said insertion section 25 of the rotary guide part 8 is advantageously axially longer than the depth of the recess 9, so that the insertion section 25 protrudes a little from the recess 9 when fully inserted, cf. 5 and 6 (b) . In the position used as intended, the rotary guide part 8 is in contact with the shoulder of the head section 26 on an outside edge contour of the recess 9, for example a flat outside of the component to be locked, and is protruding with an end section of the insertion section 25 on a back or inside of the component the recess.

How Fig. 4 shows, third locking means 15 are provided on the rotary guide part 8 in order to lock the rotary guide part 8 at the said recess 9 and to fix it in the intended position. Said latching means 15 can include, in particular on the circumference of the insertion section 25, radially projecting latching projections 16, which can be formed, for example, by integrally molded spring tongues.

According to the invention, a plurality of such locking projections 16 are staggered one behind the other in the axial insertion direction in order to be able to lock the rotary guide part 8 in a precisely fitting manner on body parts of different thicknesses or recesses 9 of different depths. For this purpose, the mentioned locking projections 16 are spaced to different degrees from the shoulder of the head section 26 of the rotary guide part, so that the different locking projections 16 define a different gap dimension to the mentioned head section 26. Depending on how thick the edge contour surrounding the recess 9 is, another locking projection 16 latches like this Fig. 6 (b) shows.

Advantageously, the aforementioned locking projections 16 are arranged in groups over the circumference of the rotary guide part 8, for example in pairs on opposite sides, so that at least two are always the same distance from the Shoulder of the head portion 26 spaced locking projections can snap into place.

The Fig. 4 also shows various locking parts 7 which can be locked with the actuating bolts 6 and which can optionally be locked with the actuating bolt 6 in order to be able to adapt the locking device 1 to various devices to be locked. In a further embodiment (not shown in the figures), a locking part 7 can have a hook-shaped section which can be brought into engagement with a corresponding counterpart in a locked position.

How, for example, from the Figures 4 , 5 and 6 results, the locking device 1 can be mounted as follows: First, the rotary guide part 8 is inserted from the outside into the recess 9 on the device 3 to be locked, for example the door 2 shown, so that the locking projections 16 latch and the rotary guide part 8 is positioned exactly on the door 2 is held.

Then the actuating pin 6 is inserted into the rotary guide part 8. If necessary, the actuating bolt 6 can also be inserted even before the rotary guide part 8 is inserted. How Fig. 6 (b) shows, locking means 27 can latch or hold the actuating pin 6 axially in the rotary guide part 8. Said latching means 27 can comprise, for example, an annular projection in the through bore 23 of the rotary guide part 8 and an annular constriction on the actuating pin 6, which snap into the rotary guide part 8 when the intended axial position of the actuating pin 6 is reached, axially fixed about the actuating pin 6, but around that To keep the axis of rotation 28 of the actuating pin 6 rotatable. Alternatively, an annular latching projection could also be provided on the actuating bolt 6, which can snap into an annular groove or another latching contour on the rotary guide part 8.

From the opposite side of the component to be locked, in particular thus from the inside, the locking part 7 is then on the actuating bolt 6 axially attached and pushed so far on the bolt until the locking part 7 from Fig. 6 (a) Obtained, desired axial position has reached. Here, the locking means 10 engage in locking engagement and fix the locking part 7 axially on the actuating bolt 6.

Due to the contouring of the latching section 6b deviating from the circular shape and a corresponding contouring of the counter-contour piece 13 also deviating from the circular shape, the locking part 7 is simultaneously connected in a rotationally fixed manner to the actuating bolt 6, so that the locking part 7 between a locking and a non-locking one by rotating the actuating bolt 6 locking position can be moved back and forth. Here, the transverse rib 21 on the actuating head 17 and one of the transverse grooves 22 on the rotary guide part 8 come into engagement in order to hold the actuating bolt 6 and thus the locking part 7 in the locking position and the non-locking position.

In order to dismantle the locking device 1, the procedure can basically be carried out in the reverse order of the assembly, in order for the end customer to then install the desired final lock into the recess 9, for example.

This in Fig. 7 The game device shown is designed in the embodiment shown as a so-called upright device which comprises a cabinet-like device housing in which a display unit in the form of two large screens and an intermediate display field for displaying game information is provided in a manner known per se. A protruding control panel section is provided on the front of the device housing in a lower half, which can include control buttons for game control. Furthermore, a mouthpiece for entering banknotes into a banknote processing device is provided on the front of the device housing, for example in the area of the control panel section mentioned. In the embodiment shown, a housing door is pivotally connected to the basic body of the housing about an upright axis. The housing door has a recess 9 into which the locking device 1 can be inserted.
